Preface and forward-looking statements

This presentation includes certain highlights of, and also material supplemental to, State Street Corporation’s news release announcing its third quarter 2020 financial results. That news release contains a more detailed discussion of many of the matters described in this presentation and is accompanied by detailed financial tables. This presentation is designed to be reviewed together with that news release, which is available on State Street’s website, at http://investors.statestreet.com, and is incorporated herein by reference.

This presentation (and the conference call accompanying it) contains forward-looking statements as defined by United States securities laws. These statements are not guarantees of future performance, are inherently uncertain, are based on assumptions that are difficult to predict and have a number of risks and uncertainties. The forward-looking statements in this presentation speak only as of the time this presentation is first furnished to the SEC on a Current Report on Form 8-K, and State Street does not undertake efforts to revise forward-looking statements. See “Forward-looking statements” in the Appendix for more information, including a description of certain factors that could affect future results and outcomes.

Certain financial information in this presentation is presented on both a GAAP basis and on a basis that excludes or adjusts one or more items from GAAP. The latter basis is a non-GAAP presentation. Refer to the Appendix for explanations of our non-GAAP financial measures and to the Addendum for reconciliations of our non-GAAP financial information.

Endnotes1. New asset servicing mandates, including announced front-to-back investment servicing clients, may be subject to completion of definitive agreements, approval of applicable boards and shareholders and customary regulatory approvals. New

asset servicing mandates and servicing assets remaining to be installed in future periods exclude new business which has been contracted, but for which the client has not yet provided permission to publicly disclose and is not yet installed. These excluded assets, which from time to time may be significant, will be included in new asset servicing mandates and reflected in servicing assets remaining to be installed in the period in which the client provides its permission. Servicing mandates and servicing assets remaining to be installed in future periods are presented on a gross basis and therefore also do not include the impact of clients who have notified us during the period of their intent to terminate or reduce their relationship with State Street, which from time to time may be significant. New business in assets to be serviced is reflected in our AUC/A after we begin servicing the assets, and new business in assets to be managed is reflected in our AUM after we begin managing the assets. As such, only a portion of any new asset servicing and asset management mandates may be reflected in our AUC/A and AUM as of any particular date specified. Generally, our servicing fee revenues are affected by several factors including changes in market valuations, client activity and asset flows, net new business and the manner in which we price our services. We provide a range of services to our clients, including core custody services, accounting, reporting and administration and middle office services, and the nature and mix of services provided affects our servicing fees. The basis for fees will differ across regions and clients. The industry in which we operate has historically faced pricing pressure, and our servicing fee revenues are also affected by such pressures today. Consequently, no assumption should be drawn as to future revenue run rate from announced servicing wins or new servicing business yet to be installed, as the amount of revenue associated with AUC/A can vary materially. Management fees generally are affected by our level of AUM and differ based upon the nature, type and investment strategy of the investment product. Management fee revenue is more sensitive to market valuations than servicing fee revenue, as a higher proportion of the underlying services provided, and the associated management fees earned, are dependent on equity and fixed-income security valuations. Additional factors, such as the relative mix of assets managed, may have a significant effect on our management fee revenue. While certain management fees are directly determined by the values of AUM and the investment strategies employed, management fees may reflect other factors, including performance fee arrangements, as well as our relationship pricing for clients.

2. Company-wide productivity and efficiency gross savings of 5% based on an expenses ex-notable items basis for the comparison between 3Q20YTD and 3Q19YTD. 3Q20YTD expenses ex-notable items of $6,411M decreased (2)% from 3Q19YTD expenses ex-notable items of $6,547M. The decrease is primarily driven by gross savings worth ~(5)%, partially offset by incremental investments and variable costs worth ~3%. Financial metrics ex-notable items are non-GAAP measures. For further details on explanations and reconciliations of our non-GAAP measures, refer to Reconciliation of notable items and Non-GAAP measures included in the Appendix.

3. In accordance with ASU 2016-13, the Provision for credit losses for 2Q20 and 3Q20 includes the provision on funded and unfunded commitments as well as HTM securities. For 3Q19, the provision for credit losses on unfunded commitments of $0 is included within Total expenses.

4. The index names listed are service marks of their respective owners.5. Industry data is provided for illustrative purposes only. It is not intended to reflect State Street's or its clients' activity and is indicative of only selected segments of the entire industry. The data provider for North America industry flows were

changed to Morningstar from other providers in 3Q20 for consistency across regions and other efficiency considerations. Data collection and tabulation methodologies among data providers differ. All periods presented reflect data sourced from Morningstar. Prior period data therefore differs from data previously presented, which was sourced from other data providers. Morningstar data includes long-term mutual funds, ETF’s and Money Market funds. Mutual fund data represents estimates of net new cash flow, which is new sales minus redemptions combined with net exchanges, while ETF data represents net issuance, which is gross issuance less gross redemptions. Data for Fund of Funds, Feeder funds and Obsolete funds were excluded from the series to prevent double counting. Data is from the Morningstar Direct Asset Flows database. The long-term fund flows reported by Morningstar in North America are composed of US domiciled Market flows mainly in Equities, Allocation and Fixed Income asset classes. 3Q20 data for North America (US domiciled) includes Morningstar actuals July and August and Morningstar estimates for September 2020.

6. FX trading services includes Brokerage and other revenue.7. Revenue and pre-tax income reflects the application of ASC 606. Revenue recognition under ASC 606 results in the acceleration of a significant portion of revenues for on-prem software agreements when a client goes live or renews their

contract with us. The amount of revenue recognized in any given quarter will be driven in large part by client activity, including agreements that renew or are installed in that quarter.8. CRD bookings, as presented in this presentation, represent signed annual recurring revenue contract value excluding bookings with affiliates, including SSGA. CRD revenue derived from affiliate agreements is eliminated in consolidation for

financial reporting purposes.9. Average contract term and deal size comparison based on new contracts between FY2017 to 3Q18 (CRD pre-acquisition) and 4Q18 to 3Q20 (CRD post-acquisition). Contracts exclude affiliates. New SaaS client comparison based on the

number of SaaS clients at year-end 2019 as compared to September 2020.10. Revenue synergy target of $75-85M in 2021 mainly represents opportunities to enhance the distribution of State Street products and capabilities to CRD clients, cross sell CRD into State Street client base, expand share of wallet across our

combined client base, bundle services to clients seeking an integrated experience and expand combined and integrated capabilities into new client segments. Cost synergy target of ~$55-65M in 2021 is net of expenses and cost to achieve, excluding restructuring charges, on a pre-tax basis. All targets as announced on July 20, 2018.

11. NII is presented on a GAAP-basis. NIM is presented on an FTE-basis. Refer to the Addendum for reconciliations of NII FTE-basis to NII GAAP-basis on the Average Statement of Condition. NIM (ex-MMLF) is presented on a FTE-basis and also excludes NII of $12.1M and $1.7M for 2Q20 and 3Q20, respectively.

12. Other includes other expenses and amortization of intangible assets.13. For purposes of this presentation, prior period balances have been revised to reflect the carrying value of the securities, including available-for-sale securities at fair value, rather than amortized cost.14. Unless otherwise noted, all capital ratios referenced on this slide and elsewhere in this presentation refer to State Street Corporation, or State Street, and not State Street Bank and Trust Company, or State Street Bank. The lower of capital

ratios calculated under the Basel III advanced approaches and under the Basel III standardized approach are applied in the assessment of our capital adequacy for regulatory purposes. Standardized approach ratios were binding for 3Q19, 2Q20 and 3Q20. Refer to the Addendum included with this presentation for a further description of these ratios. September 30, 2020 capital ratios are presented as of quarter-end and are estimated as of October 16, 2020.

15. State Street received an SCB requirement of 2.5%. The SCB requirement is effective as of October 1, 2020.16. Subject to annual CCAR process conducted by the Board of Governors of the Federal Reserve System. CCAR cycles run from mid-year to mid-year.17. Includes drawn loans, gross. Line items may not sum to total due to rounding.18. CRE and Other category includes Commercial Real Estate, Alternative Financing, Municipal Loans, and other.19. Calculated under the incurred loss methodology.

Forward-looking statementsThis presentation (and the conference call referenced herein) contains forward-looking statements within the meaning of United States securities laws, including statements about our goals and expectations regarding our business, financial and capital condition, results of operations, strategies, the financial and marketoutlook, dividend and stock purchase programs, governmental and regulatory initiatives and developments, expense reduction programs, new client business, and the business environment. Forward-looking statements are often, but not always, identified by such forward-looking terminology as “outlook,” “guidance,”“expect,” “priority,” “objective,” “intend,” “plan,” “forecast,” “believe,” “anticipate,” “estimate,” “seek,” “may,” “will,” “trend,” “target,” “strategy” and “goal,” or similar statements or variations of such terms. These statements are not guarantees of future performance, are inherently uncertain, are based on current assumptionsthat are difficult to predict and involve a number of risks and uncertainties. Therefore, actual outcomes and results may differ materially from what is expressed in those statements, and those statements should not be relied upon as representing our expectations or beliefs as of any time subsequent to the time thispresentation is first issued.

Important factors that may affect future results and outcomes include, but are not limited to: the financial strength of the counterparties with which we or our clients do business and to which we have investment, credit or financial exposures or to which our clients have such exposures as a result of our acting as agent,including as an asset manager or securities lending agent; the significant risks and uncertainties for our business, results of operations and financial condition, as well as our regulatory capital and liquidity ratios and other regulatory requirements, caused by the COVID-19 pandemic, which will depend on several factors,including the scope and duration of the pandemic, its influence on the economy and financial markets, the effectiveness of our work from home arrangements and staffing levels in operational facilities, challenges associated with our return to office plans such as maintaining a safe office environment and integrating at-home and in-office staff, the impact of market participants on which we rely and actions taken by governmental authorities and other third parties in response to the pandemic and the impact of lower equity market valuations on our service and management fee revenue; increases in the volatility of, or declines in the levelof, our NII; changes in the composition or valuation of the assets recorded in our consolidated statement of condition (and our ability to measure the fair value of investment securities); and changes in the manner in which we fund those assets; the volatility of servicing fee, management fee, trading fee and securitiesfinance revenues due to, among other factors, the value of equity and fixed-income markets, market interest and FX rates, the volume of client transaction activity, competitive pressures in the investment servicing and asset management industries, and the timing of revenue recognition with respect to software andprocessing fees revenues; the liquidity of the U.S. and international securities markets, particularly the markets for fixed-income securities and inter-bank credits; the liquidity of the assets on our balance sheet and changes or volatility in the sources of such funding, particularly the deposits of our clients; and demandsupon our liquidity, including the liquidity demands and requirements of our clients; the level, volatility and uncertainty of interest rates; the expected discontinuation of Interbank Offered Rates including London Interbank Offered Rate (LIBOR); the valuation of the U.S. dollar relative to other currencies in which we recordrevenue or accrue expenses; the performance and volatility of securities, credit, currency and other markets in the U.S. and internationally; and the impact of monetary and fiscal policy in the U.S. and internationally on prevailing rates of interest and currency exchange rates in the markets in which we provide services toour clients; the credit quality, credit-agency ratings and fair values of the securities in our investment securities portfolio, a deterioration or downgrade of which could lead to impairment of such securities and the recognition of a provision for credit losses in our consolidated statement of income; our ability to attract andretain deposits and other low-cost, short-term funding; our ability to manage the level and pricing of such deposits and the relative portion of our deposits that are determined to be operational under regulatory guidelines; our ability to deploy deposits in a profitable manner consistent with our liquidity needs, regulatoryrequirements and risk profile; and the risks associated with the potential liquidity mismatch between short-term deposit funding and longer term investments; the manner and timing with which the Federal Reserve and other U.S. and non-U.S. regulators implement or reevaluate the regulatory framework applicable to ouroperations (as well as changes to that framework), including implementation or modification of the Dodd-Frank Act and related stress testing and resolution planning requirements and implementation of international standards applicable to financial institutions, such as those proposed by the Basel Committee andEuropean legislation (such as Undertakings for Collective Investments in Transferable Securities (UCITS) V, the Money Market Fund Regulation and the Markets in Financial Instruments Directive II/Markets in Financial Instruments Regulation); among other consequences, these regulatory changes impact the levels ofregulatory capital, long-term debt and liquidity we must maintain, acceptable levels of credit exposure to third parties, margin requirements applicable to derivatives, restrictions on banking and financial activities and the manner in which we structure and implement our global operations and servicing relationships. Inaddition, our regulatory posture and related expenses have been and will continue to be affected by heightened standards and changes in regulatory expectations for global systemically important financial institutions applicable to, among other things, risk management, liquidity and capital planning, cyber-security,resiliency, resolution planning and compliance programs, as well as changes in governmental enforcement approaches to perceived failures to comply with regulatory or legal obligations; adverse changes in the regulatory ratios that we are, or will be, required to meet, whether arising under the Dodd-Frank Act orimplementation of international standards applicable to financial institutions, such as those proposed by the Basel Committee, or due to changes in regulatory positions, practices or regulations in jurisdictions in which we engage in banking activities, including changes in internal or external data, formulae, models,assumptions or other advanced systems used in the calculation of our capital or liquidity ratios that cause changes in those ratios as they are measured from period to period; requirements to obtain the prior approval or non-objection of the Federal Reserve or other U.S. and non-U.S. regulators for the use, allocation ordistribution of our capital or other specific capital actions or corporate activities, including, without limitation, acquisitions, investments in subsidiaries, dividends and stock repurchases, without which our growth plans, distributions to shareholders, share repurchase programs or other capital or corporate initiatives may berestricted; geopolitical risks applicable to our operations and activities in jurisdictions globally, including emerging markets and economies, that have the potential to disrupt or impose costs, delays or damages upon our, our clients', our counterparties' and suppliers' and our infrastructure providers' respective operations,activities and strategic planning and to compromise financial markets and stability; changes in law or regulation, or the enforcement of law or regulation, that may adversely affect our business activities or those of our clients or our counterparties, and the products or services that we sell, including, without limitation,additional or increased taxes or assessments thereon, capital adequacy requirements, margin requirements and changes that expose us to risks related to our operating model and the adequacy and resiliency of our controls or compliance programs; cyber-security incidents, or failures to protect our systems and our, ourclients' and others' information against cyber-attacks, that could result in the theft, loss, unauthorized access to, disclosure, use or alteration of information, system failures, or loss of access to information; any such incident or failure could adversely impact our ability to conduct our businesses, damage our reputation andcause losses, potentially materially; our ability to expand our use of technology to enhance the efficiency, accuracy and reliability of our operations and our dependencies on information technology; to replace and consolidate systems, particularly those relying upon older technology, and to adequately incorporate cyber-security, resiliency and business continuity into our operations, information technology infrastructure and systems management; to implement robust management processes into our technology development and maintenance programs; and to control risks related to use of technology, including cyber-crime and inadvertentdata disclosures; our ability to identify and address threats to our information technology infrastructure and systems (including those of our third-party service providers); the effectiveness of our and our third party service providers' efforts to manage the resiliency of the systems on which we rely; controls regarding theaccess to, and integrity of, our and our clients' data; and complexities and costs of protecting the security of such systems and data; our ability to control operational and resiliency risks, data security breach risks and outsourcing risks;

economic or financial market disruptions in the U.S. or internationally, including those which may result from recessions or political instability; for example, the United Kingdom's (U.K.) exitfrom the European Union or actual or potential changes in trade policy, such as tariffs or bilateral and multilateral trade agreements; our ability to create cost efficiencies through changes in our operational processes and to further digitize our processes and interfaces with our clients, any failure of which, in whole or inpart, may among other things, reduce our competitive position, diminish the cost-effectiveness of our systems and processes or provide an insufficient return on our associated investment; our ability to promote a strong culture of risk management, operating controls, compliance oversight, ethical behavior and governancethat meets our expectations and those of our clients and our regulators, and the financial, regulatory, reputational and other consequences of our failure to meet such expectations; the impact on our compliance and controls enhancement programs associated with the appointment of a monitor under the deferredprosecution agreement with the DOJ and compliance consultant appointed under a settlement with the SEC, including the potential for such monitor and compliance consultant to require changes to our programs or to identify other issues that require substantial expenditures, changes in our operations, payments toclients or reporting to U.S. authorities; the results of our review of our billing practices, including additional findings or amounts we may be required to reimburse clients, as well as potential consequences of such review, including damage to our client relationships or our reputation, adverse actions or penalties imposed bygovernmental authorities and costs associated with remediation of identified deficiencies; the results of, and costs associated with, governmental or regulatory inquiries and investigations, litigation and similar claims, disputes, or civil or criminal proceedings; changes or potential changes in the amount of compensation wereceive from clients for our services, and the mix of services provided by us that clients choose; the large institutional clients on which we focus are often able to exert considerable market influence and have diverse investment activities, and this, combined with strong competitive market forces, subjects us to significantpressure to reduce the fees we charge, to potentially significant changes in our AUC/A or our AUM in the event of the acquisition or loss of a client, in whole or in part, and to potentially significant changes in our revenue in the event a client re-balances or changes its investment approach, re-directs assets to lower- orhigher-fee asset classes or changes the mix of products or services that it receives from us; the potential for losses arising from our investments in sponsored investment funds; the possibility that our clients will incur substantial losses in investment pools for which we act as agent; the possibility of significant reductions inthe liquidity or valuation of assets underlying those pools and the potential that clients will seek to hold us liable for such losses;

our ability to complete acquisitions, jointventures and divestitures, including, without limitation, our ability to obtain regulatory approvals, the ability to arrange financing as required and the ability to satisfy closing conditions; the risks that our acquired businesses, including, without limitation, CRD, and joint ventures will not achieve their anticipated financial,operational and product innovation benefits or will not be integrated successfully, or that the integration will take longer than anticipated; that expected synergies will not be achieved or unexpected negative synergies or liabilities will be experienced; that client and deposit retention goals will not be met; that otherregulatory or operational challenges will be experienced; and that disruptions from the transaction will harm our relationships with our clients, our employees or regulators; our ability to integrate CRD's front office software solutions with our middle and back office capabilities to develop our front-to-middle-to-back officeState Street Alpha that is competitive, generates revenues in line with our expectations and meets our clients' requirements; the dependency of State Street Alpha on enhancements to our data management and the risks to our servicing model associated with increased exposure to client data; our ability to recognizeevolving needs of our clients and to develop products that are responsive to such trends and profitable to us; the performance of and demand for the products and services we offer; and the potential for new products and services to impose additional costs on us and expose us to increased operational risk; our ability togrow revenue, manage expenses, attract and retain highly skilled people and raise the capital necessary to achieve our business goals and comply with regulatory requirements and expectations; changes in accounting standards and practices; and the impact of the U.S. tax legislation enacted in 2017, and changes in taxlegislation and in the interpretation of existing tax laws by U.S. and non-U.S. tax authorities that affect the amount of taxes due.

Other important factors that could cause actual results to differ materially from those indicated by any forward-looking statements are set forth in our 2019 Annual Report on Form 10-K and our subsequent SEC filings. We encourage investors to read these filings, particularly the sections on risk factors, for additionalinformation with respect to any forward-looking statements and prior to making any investment decision.

Non-GAAP measures

In addition to presenting State Street's financial results in conformity with U.S. generally accepted accounting principles, or GAAP, management also presents certain financial information on a basis that excludes or adjusts one or more items from GAAP. This latter basis is a non-GAAP presentation. In general, our non-GAAP financial results adjust selected GAAP-basis financial results to exclude the impact of revenue and expenses outside of State Street’s normal course of business or other notable items, such as acquisition and restructuring charges, repositioning charges, gains/losses on sales, as well as, for selected comparisons, seasonal items. For example, we sometimes present expenses on a basis we may refer to as “expenses ex-notable items", which exclude notable items and, to provide additional perspective on both prior year quarter and sequential quarter comparisons, also exclude seasonal items. Management believes that this presentation of financial information facilitates an investor's further understanding and analysis of State Street's financial performance and trends with respect to State Street’s business operations from period-to-period, including providing additional insight into our underlying margin and profitability. In addition, Management may also provide additional non-GAAP measures. For example, we present capital ratios, calculated under regulatory standards scheduled to be effective in the future or other standards, that management uses in evaluating State Street’s business and activities and believes may similarly be useful to investors. Additionally, we may present revenue and expense measures on a constant currency basis to identify the significance of changes in foreign currency exchange rates (which often are variable) in period-to-period comparisons. This presentation represents the effects of applying prior period weighted average foreign currency exchange rates to current period results.

Non-GAAP financial measures should be considered in addition to, not as a substitute for or superior to, financial measures determined in conformity with GAAP.
